FEEDQWATER HEATER.

SPECIFICATION forming part of Letters Patent No. 398,645, dated February 26, 1889.

Application filed February 10, 18881 Serial No. 263,609. (No modela Figure l is a longitudinal section of m v iml proved f eed-wat er heater and purifier on the line l Fie'. 'l. Fie. 2 is a side view.

Fig. o is a section on the line 3 et, Fig. l. Fig. l is a section on the line 5 U, Fig. l. Fig. 5 is a secmade in this f'orin can be bent very cheaply,

tional detail. Figs. t3 and T are views of a modified form, and Fig. S is a view of another modification.

1/ is etmneeted to the feed-pipe 1]', while the others are plugged or suitably capped, to pre vent the escape ot water.

The advantage ofconstructing the spray- 'f'eed in this peculiar form is that by removing the plugs from the passages g the latter can be readily cleaned by passing the cleaners from one en d of the passages to the other, and a further advantage is that the heater can be set in any position irrespective of the water` suppl y, which can be connected to that one of the lf'our passages g which ismost convenient. The heated water escapes through the pipe 71.

The bent tubes F are steam-tubes and the saddle D is the steam-inlet, while the saddle E i the steambutlet, the bent tubes allowin for an)v amount ot' contraction and expansion and at the same time afi'ording an extended heating-surf'ace; and,furthermore, the tubes for instead of the expensive plan of ceiling 1 the tubes, whereby each section of the coilhas A is the casingot' the heater, having a base i ring, 11 and head 11', the base-ring being se- 1 the restof the tube being left cold.

to be heated and bent, my improved tube requires only the heating ot the return-bends, It will 1 thus be seen that much time and labor are saved in the bending operation alone; and, furthermore, the tubes can be placed very near together, side by side, in a heater, or the tubes 1nav be arranged not only in series side by side, but also in double rows, as shown in l Fig.

In expanding the tubes into the saddles D and E, I torni a groove, yz, around the opening l I, as shown in Fig. 5, so that as the tube is eX- panded 1t will not only form a seat at the culiar torni shown in Fig. l, being bent only y i groove 1; hence each of' the tubes has practiat the points f, `forming a return-bend and having straight portionsj". One end of each tube enters the saddle D at the lower end,

While the other end of' each tube enters the saddle E at the upper end, and the tubes are points 111 111, but also at the points 11 n in the cally four seats.

I am aware that it is not new to place two tube-sheets some distance apart with a space between them and to expand the tube in said arranged as close together as practicable, as

shown in Fig. l, thus afifording a very large heating-surface.

G is a spraytube sit nai ed, preferabl v, below the lower bend of; the tubes F, as shown in Fig. l, this tube being eruciform in shape and havin g four passages, g, the tubes of the spi-a vl i as shown in Figs. C and T, the steam in this case feed being' punctured with a number of holes,

sheets, so as to form a double sheet, as thisis shown and claimed in an application filed b v me on the fth dav of' Nav, ISST, Serial No. 311,169.

In some easesl prefer to construct the feedwater heater and purifier with what may be term ed vertical bent tubes or .serpen tines,

entering at the opening 111r in the base, passing up through the series of bent tubes F into the TOO dome P, and from this dome down the series of tubes F2 into and through the outlet-openthe two chambers.

ing N in the base, a partition, K, separating v In this ease the lower blow-offfor the water is located a short distance above the base and the spray-pipes are located as shown in Fig. 6.

I Claim as my inventiond l. The combination, in a feed-water heater, of the cylindrical Casin g, with oblong inlet and exhaust saddles inserted in the sides of said cylindrical casing and presenting internally plane faces parallel with eaeh other, and a row of serpentine tubes in said easing, the lower ends of thetubes being secured to the saddle and the upper ends of the tubes to the other saddle, all substantially as described.

2. The combination, in a feed-waterheater, of the cylindrical easing, with oblong saddles inserted therein, rows of tubes connecting said saddles, and Caps Afor the saddles, each consist# flanged tube, subst-antially as described.

3. The combination, in a feed-water heater,.

of the easing With a spray-feed device erueiform in shape and having two or more of the tubes extending to the outside of the easing, substantially as and for the purpose described.

4. The Combination, in a feed-water heater, of the easing with a spray-feeding device having four tubular arms, each arm extending to and supported by the easing, and each arln adapted to be secured to the inlet-pipe, substantially as and for the purposeV set forth.

In testimony whereof I have signed my name to this specification in the presen ce of two subscriloing` witnesses.
